How do you stop the blinking green light on a Trane oil furnace?

The blinking green light on a Trane oil furnace typically indicates that the system is in standby mode or has encountered an issue. To stop the blinking, first ensure that the furnace's power supply is on and that the thermostat is set correctly. If the light continues to blink, check for any error codes in the manual that might indicate a specific problem, such as a clogged filter or low oil supply. If necessary, reset the furnace according to the manufacturer's instructions or contact a professional technician for assistance.
